The Greek roots

ἁψίς
hapsís
arch, loop, wheel rim
+
ἅπτειν
háptein
to fasten, join

Literally: a joining, a loop

The story of the word

ἁψίς was a loop, an arch, the rim of a wheel, anything bent round and fastened at the join. Astronomers kept the Latin form: the apsides of an orbit are its turning points, nearest and farthest, which is why an aphelion has the same ancestor as a cathedral. The verb behind it, ἅπτειν, to fasten, also gives synapse, the place where two nerve cells make contact without quite touching.
